Problem: Mercury(I) ions (Hg22+) can be removed from solution by precipitation with Cl–. Suppose that a solution contains aqueous Hg2(NO3)2.Write net ionic equation to show the reaction of aqueous Hg2(NO3)2 with aqueous sodium chloride to form solid Hg2Cl2 and aqueous sodium nitrate.

FREE Expert Solution

Hg2(NO3)2 (aq) + NaCl (aq) → Hg2Cl2 (s) + NaNO3 (aq)


Hg2(NO3)2 (aq) → Hg22+ (aq) + NO3- (aq)

NaCl (aq) → Na+ (aq) + Cl- (aq)

NaNO3 (aq) → Na+ (aq) + NO3- (aq)
